ADJUSTABLE ROOFING-TONGS.

Specification of Letters Patent.

Patented Dec. 10,1907.

Application filed May 1'7. 1906. Serial No. 317,330-

To all whom it may concern:

Be it known that I, PI-IlLIP EMRIOH, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in AdjustableRoofing-Tongs, of which the following is a specification.

My invention relates to means for adjusting the tongs to produce varyingsizes of seams.

The object of my invention is to provide roofing tongs which are adaptedto be easily and conveniently adjusted whereby a single pair of tongsmay take the place of several tongs of different sizes and whereby theadjustments may be made to produce any width of seam desired.

My invention consists in providing roofing tongs with an adjustable gageat each end to limit the extent of metal to form the seam which may beinserted between the jaws of the tongs and to be readily moved to varythe width of said seam to any desired dis- .tance.

My invention also consists in the parts and 111 the construction,combination and arrangement of parts as set forth-and claimed.

In the drawings which serve to illustrate my invention: Figure 1 is aperspective view of the gage. Fig. 2 is a rear view showing the flange.Fig. 3 is a side view of a pair of roofing tongs embodying my invention.Fig. 4 is a rear view of one of the jaws showing means for fastening thegage thereto.

Fig. 5 shows a modified form of my invention. Fig. 6 shows amodification in which the scale is placed upon one of the jaws. Fig. 7is an end view of the device when closed. Fig. 8 is a similar view whenopen. Fig. 9 is another modification showing the scale'on the jaw uponwhich the gage is mounted.

My invention is preferably constructed substantially as follows: Thejaws 1 and 2 of the tongs are constructed in the ordinary manner withbevel edges 3 and 4 respectively to more readily grasp the work exceptthat the jaw 1 is cut away at each end to make it shorter where cut awaythan the correspondin part of the opposing jaw 2 as in Fig. 3 w 'chshows each end of jaw 1 entirely cut away or as in Fig. 5 which showseach end of jaw 1 partly cut away the beveled edge 3 being retained tooppose the corresponding beveled edge 4 of jaw 2 when the same arebrought to bear upon the work. The parts cut away at each end of jawg lleave a space 5 at one end and a space 6 at the other end thereof toreceive adjustable gages 7 and 8 respectively. Each adjustable gage isformed in the shape shown in Fig. 1 with a body 9 having a longitudinalslot 10 therein to receive a bolt and permit of lengthwise adjustment ofsaid gage, a channel 11 adjacent said slot adapted to receive a nut andhold it from turning, a stop 12 to limit the distance which the work tobe operated upon may be inserted between said jaws and also prevent itfrom passing too far when said jaws are open and a flange 13 to preventsaid work from passing between said adjustable gage and jaw 2 and toassist in holding said gage more firmly in adjusted position.

A scale 14 is provided upon each gage or upon one of the jaws adjacentto said gage to enable each gage to be adjusted and set alike to measureany'width of seam desired from the smallest part of an inch up to thefull limit of the gage. Each gage is secured in adjusted position asshown in- Figs.3, 4 and 5 by means of a screw bolt 15 taking through abolt hole 16 in jaw 2 and longitudinal slot 10 in said gage into nut 17resting in channel 11 in said ga e whereby said nut is held from turninwhfie said screw bolt is being turned in sai nut to tighten or loosenthe gage. The head of the screw bolt 15 is preferably counter-sunk injaw 2 as shown by dotted lines in Fig. 7.

To hold the gage firmly and securely in fixed position simply turn thescrew bolt by means of a screw driver until the nut has been drawntightly against the gage. The wear upon the gage is very slight and ofsuch a nature as not to affect its accuracy or efficiency, since anywear is taken up by the nut and screw bolt in the successiveadjustments.

Some of the advantages of 'my construction are its economy in cost ofmanufacture and its extreme simplicity and convenience in adjusting toset it for any particular size of seam desired, down to a small part ofan inch.

A desirable feature of my invention consists in-the rapidity withwhichthe gages ma be reset or adjusted to make a different wi th of seam.

.By having the tongs constructed as described with my adjustable agesapplied thereto the same are adapted to take the place of eight or moresimilar tongs when constructed with non-adjustable gages and the mannerof constructing and applying my adjustable gages renders the tongs eX-tremely light, which is an important feature since they should not beany heavier than is necessary to accomplish the work desired in orderthat they may be conveniently carried and handled by the operator. Itwill be seen that a great saving will result to the user by beingrequired to purchase only one pair of tongs in place of eight or more,and a further advantage results in the operator having to carry only onepair upon roofs or elsewhere instead of a large number.

The operation of adjusting the gages is ex tremely simple and consistsmerely in turning screw bolt 15 by a screw driver first in one directionto loosen the adjustable gage and then in the reverse direction totighten it after ithas been adjusted to the desired point upon thescale.

To obtain any desired width of seam move the gage lengthwise, as, forinstance, to obtain a one-half inch seam adjust the gage lengthwiseuntil the gage mark ac on the jaw 1 is opposite the half inch mark onthe scale as shown in Fig. 3. To set the gage when the scale is upon thejaw merely adjust the outer edge of the stop 12 opposite the point uponthe scale which indicates the width of seam desired, as for instance, athree-fourth inch seam is indicated by the position of the gage in Figs.6 and 9. After the gage has been set for the required width of seam theoperator takes the tongs by the levers 18 and 19 and opens the jaws fromthe position shown in Fig. 7 to the position shown in Fig. 8 and slidesthe jaws over the edge of a piece of tin or sheet metal to be operatedupon until it comes into contact with the stop 12 when the jaws areclosed and the levers brought to an upright position or at right anglesto the surface upon which the metal is resting. This produces thenecessary bend in the metal and such as is contemplated by the use ofthis tool.

I claim:

1. In adjustable roofing tongs, a pair of jaws one of which projectsbeyond the other at each end, an adjustable gage at each end of theshorter jaw, means for securing each gage to the longer jaw to hold itin an adjusted position thereon, and a scale on each adjustable gage bywhich to set said gages and measure the width of seam, substantially asset forth.

2. In adjustable roofing tongs, a pair of jaws one of which projectsbeyond the other at each end, an adjustable gage upon the projectingparts of the longer jaw at each end of the shorter jaw, means foradjusting the gage to hold it in adjusted position upon the longer jawand adjacent the ends of the shorter jaw, a scale upon each gage, and agage mark upon the shorter aw adapted to register with the respectivegraduations of the scale, substantially as set forth.

3. In adjustable roofing tongs, a pair of jaws one of which is cut awayat each. end, an adjustable gage at each end of said cut away jaw, meansfor adjusting each gage to hold it in adjusted position upon the awwhich not cut away and a flange upon said gage adapted to take over andbear against the jaw which is not cut away.

4. In adjustable roofing tongs, a jaw cut away at each end, an opposingjaw, an adjustable gage secured to the opposing jaw at each end withinthe space cut away, said gage having a slot, a screw bolt taking througha hole in said opposing jaw and through said slot, a nut adapted toengage said screw bolt, means upon said gage adapted to engage said nutwhereby it is held from turning and a stop to limit the extent ofinsertion of the metal between said jaws.

5. In adjustable roofing tongs, a jaw cut away at each end, an opposingjaw, an adjustable gage adapted to occupy the cut away space at each endand rest against the end of said cut away jaw and the inner surface ofthe opposing jaw, said adjustablegage having a slot, means for securingsaid gage to said opposing jaw and a flange upon said gage adapted toextend over the end of said opposing jaw whereby the metal plateoperated upon is prevented from passing between said jaw and gage andwhereby said gage is more firmly held in adjusted position.

6. In adjustable roofing tongs, a jaw cut away at each end, an opposingjaw extending opposite parts cut away, an adjustable gage adapted totake into the space cut away and bear against the end of the cut awayjaw and the inner surface of the opposing jaw, a screw bolt secured tosaid opposing jaw adapted to pass through a longitudinal slot in theadjustable gage, a nut secured to said bolt adapted to rest within achannel in said nut to hold it from turning and a scale upon one side ofthe gage adaptedv to measure the width of seam desired.
